Help please! Geometry stuff. Fill out the chart.

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

Ithink i know it but i want to be sure so can you me out ?
